Unusual for gas leaks not to be related to hack plumbers.

when you run 60 plus pounds of gas through any gas appliance made for 1/4 pound and it blows the gas valve out and fills house with gas..house goes boom....I think the gas company crewed up and put high pressure gas through low pressure service pipes...national grid just put all new pipe in the ground where I live and upgraded from low pressure to high pressure with new regulators at every house, but there is still miles of low pressure pipe in the ground, so if they made a mistake with a cross connection and sent high pressure to houses that will happen...im curious to see what the cause is from..

The Massachusetts Emergency Management Agency blamed the fires on gas lines that had become over-pressurized but said investigators were still examining what happened.

The San Bruno fire was caused by old lines with suspect welds giving under excess pressure. And, the utility (PG&E) was well aware of the danger beforehand.

I can understand a regulator not holding high pressure, but pipe is pipe. A steel pipe shouldn't break apart if pressure goes from 1 psi to 65 psi.


Something doesn't add up with this scenario. I don't think that we have enough facts.

here on long island some of the gas lines are in the thousands of pounds of pressure, usually from national grid facility to facility, but cross connections can happen, what happened in boston are the appliance regulators blowing from the high pressure..not the pipes bursting..but some or many of the old gas main pipes are lucky to hold low pressure because they are so old...lets not talk about the water mains either..or infrastructure in the US is crumbling, so get use to more of these disasters ..its still cheaper to pay the damage than fix the system..

I am at a loss here too.... in our town in comes to the house in high pressure and gets kicked down to a few ounces through the gas regulator at the meter---

- so can the regulators blow from high pressure

or are these older lines you are talking about in the system with only low pressure going through them have no regulators at the meters in case of a spike in pressure from a cross connection???

on long island, the low pressure( 1/4lb) meters run straight through, no safteys incase high pressure is piped to them, just what happened in boston im figuring...national grid seems to be changing over to all high pressure mains and services with regulators, I believe the regulators have a relief valve that vents the gas to the outside incase they let loose...

These were low pressure (1/2 psi) services supplied to the homes and businesses (old infrastructure) the gas valves and gas pipes became compromised with 95PSI (estimated) and filled many structures with gas.

Sad situation up here and itís getting colder by the day.
